4 Series Coupe

Don't get confused by yet another numerical addition to the BMW lineup. The German automaker announced months ago that the upcoming two-door version of its 3 Series sedan will be rechristened the 4 Series. The apparent logic behind this change is simply to differentiate the coupe from its sedan counterpart just like Audi has done with its A4/A5. Everybody getting this? Good, because Bimmerpost is reporting that the 4 Series concept will debut this January at the Detroit Auto Show.

We've also seen quite a few spy shots of test mules on the road, so don't be surprised to see the production version itself arrive sometime later next year. Like the outgoing 3 Series two-door, the new 4 Series will also be available in both coupe and cabrio body styles as well as the M high performance version, now redubbed the M4. We also know that BMW is currently developing the 4 Series Gran Coupe, a four-door version of the same car only with a sleeker roofline. Expect to see the latter arrive for model year 2015.
